Consider the following hypotheses: H0: 12.6 HA: > 12.6 A sample of 25 observations
Question:
Consider the following hypotheses:
H0: µ ≤ 12.6
HA: µ > 12.6
A sample of 25 observations yields a sample mean of 13.4. Assume that the sample is drawn from a normal population with a known population standard deviation of 3.2.
a. Calculate the p-value.
b. What is the conclusion if α = 0.10?
c. Calculate the p-value if the above sample mean was based on a sample of 100 observations.
d. What is the conclusion if α = 0.10?
